Find current through battery when switch is closed.

Find current through 4V battery

Consider the situation shown in figure (31-E23 ) . The switch S is open for a long time and then closed . (a) Find the charge flown through the battery when the switch S is closed (b)Find the work done by the bettery .

For the given circuit the current i through the battery when the key in closed and the steady state has been reached is _______ .

For the given circuit the current i through the battery when the key in closed and the steady state has been reached is _______ .

Consider the situation shown in the figure. The switch S is open for a long time and then closed and again steady state reached then (a) Find the charge flown through the battery after the switch S is closed. (b) Find the charge flown through the switch S from B to A. (c) Find the work done by the battery after the switch S is closed. (d) Find the change in energy stored in the system of capacitors. (e) Find the heat developed in the system after the switch S is closed.

In the circuit shown the cell is ideal. The codil has an inductance of 2H and will blow when the current through it reaches 5a. The switch is closed at t=0. Find the time (in second)n when fuse will blow.

In cirucit shown in figure-5.111, find the current through battery just after closing the switch and after a long time in steady state.

Find current through the battery (a) just after the switch is closed (b) long after the switch has been closed
